That is, even when the inclined portion 20f is provided, a gap h2 corresponding to the launching operation is provided between the tip portion of the inclined portion 20f and the bottom surface portion 31b of the magazine 31.

  As shown in FIG. 2, at least one guide member 40 is provided on the upper surface portion 20 t of the beam portion 20. Here, one guide member 40 is provided at a substantially central portion in the width direction X of the upper surface portion 20 t of the beam portion 20. The guide member 40 is preferably provided at a substantially central portion in the width direction X of the upper surface portion 20t of the beam portion 20, but may be provided at a location other than the central portion or two or more. .

  Specifically, as shown in FIG. 2, the guide member 40 includes a pair of side surface portions 40 s and 40 s and an upper surface portion 40 t provided between the side surface portions 40 s and 40 s. (U-shaped). Furthermore, as shown in FIG. 4, the guide member 40 is supported by a guide support portion 41 having side surface portions 40 s, 40 s provided on the upper surface portion 20 t of the beam portion 20 so as to be rotatable around a support shaft 42. Further, the guide member 40 is provided with a support shaft 43 between the side surface portions 40s, 40s. Further, a biasing member 44 such as a spring for biasing the guide member 40 is attached between the support shaft 47 of the guide support portion 41 and the support shaft 43 of the guide member 40. Therefore, even if the guide member 40 is urged by the urging member 44 and is flipped up and rotated to one end side in the height direction Z, the guide member 40 is high so that the side surface portion 40s contacts the convex portion 12. Even if it is rotated to the other end side in the vertical direction Z, it can stay at that position.

  Further, as shown in FIG. 4, a guide portion 45 is formed on the side surface portion 40 s of the guide member 40 to guide one end portion in the length direction Y of the paper 2 to the insertion port 21. The guide portion 45 protrudes toward the other end side in the height direction Z, and for example, the guide member 40 before the paper 2 is arranged on the base portion 10 is rotated to the maximum in one end side in the height direction Z. In this state, the lower surface portion 45b is disposed on the other end side in the height direction Z with respect to the bottom surface portion 31b of the magazine 31 of the stapler portion 30, and is disposed on the other end side in the length direction Y with respect to the beam portion 20. The upper surface portion 20t (the tip portion of the inclined portion 20f) is arranged to be substantially the same height or lower. Therefore, when one end portion of the paper 2 in the length direction Y is inserted into the insertion opening 21, the guide member 45 causes the one end portion of the paper 2 in the length direction Y to be the bottom portion of the magazine 31, for example. 31b can be prevented from being inserted into the gaps h1 and h2 between the upper surface portion 20t of the beam portion 20 (the tip portion of the inclined portion 20f), and one end portion in the longitudinal direction Y of the sheet 2 is inserted through the insertion opening. 21 can be reliably guided. Further, the guide portion 45 has a lower surface portion 45b substantially parallel to the guide portion 12b on one end side in the length direction Y of the convex portion 12 when the guide member 40 is rotated to the maximum in one end side in the height direction Z. It is formed to become. Therefore, the guide member 40 can smoothly guide one end portion of the sheet 2 in the length direction Y to the insertion port 21. Therefore, the saddle stitching machine 1 can improve workability by improving the insertability of the paper 2.

  Further, as shown in FIG. 4, a pressing holding portion 46 that presses and holds the paper 2 disposed in the base portion 10 against the base portion 10 is formed on the side surface portion 40 s of the guide member 40. The pressing holding portion 46 is a notch formed in the side surface portion 40 s of the guide member 40 in, for example, a V shape, a U shape, an arc shape, a semicircular shape, and the like. It is formed at a position corresponding to the top surface portion 12 a of the convex portion 12. Therefore, as shown in FIG. 5, when the guide member 40 is rotated to the other end side in the height direction Z after the paper 2 is disposed on the base portion 10, the press holding portion 46 has the fold 2 a of the paper 2. The paper 2 placed on the base 10 can be pressed and held against the base 10 while aligning the crease 2a of the paper 2 with the clincher 11.

  Further, as shown in FIG. 2, the convex portion 12 of the base portion 10 is provided with a width direction positioning portion 50 that is formed to be slidable in the width direction X and that positions the paper 2 in the width direction X. . The width direction positioning portion 50 is provided in a side view substantially L-shaped sliding portion 51 that slides on the convex portion 12 of the base portion 10 and the sliding portion 51. And a reference portion 52 that serves as a reference in the width direction when arranged in the. The sliding portion 51 includes a first sliding portion 51a formed along the guide portion 12b on one end side of the convex portion 12, and a first portion formed along the guide portion 12b on the other end side of the convex portion 12. Two sliding portions 51b, and is slid in the width direction X by the user. The reference portion 52 is provided so as to be orthogonal to the first sliding portion 51a. The width direction positioning part 50 is formed on the convex part 12 of the base part 10 by using a known method such as a sheet-like magnet on the lower surface of the first sliding part 51a or the first sliding part 51a and the second sliding part 51b. It is attached. Therefore, the user aligns the sliding portion 51 or the reference portion 52 with a mark (not shown) or the like attached so as to correspond to the size in the width direction X of various sheets 2 for saddle stitching. After the width direction positioning portion 50 is slid, the paper 2 is placed on the base portion 10 while being in contact with the reference portion 52, whereby the paper 2 can be easily positioned in the width direction X.

<3. Explanation of saddle stitching method using saddle stitcher>
Next, a saddle stitching method for the sheet 2 using the saddle stitcher 1 will be described.

  First, as shown in FIG. 2, the saddle stitching machine 1 performs width direction positioning so that the reference portion 52 is aligned with a mark attached so as to correspond to the size in the width direction X of the sheet 2 on which saddle stitching is performed. The part 50 is slid in the width direction X. At this time, the guide member 40 is flipped up to one end in the height direction Z so as not to hinder the subsequent sheet placement operation.

  Next, as shown in FIG. 1, in the saddle stitching machine 1, the paper 2 is disposed on the base portion 10. Specifically, the sheet 2 has one end in the longitudinal direction Y of the sheet 2 inserted through the insertion port 21 of the beam portion 20, and the fold 2 a and the convex portion 12 are engaged with each other to guide the guide portion 12 b of the convex portion 12. Is arranged on the base portion 10 while being in contact with the reference portion 52 of the width direction positioning portion 50, so that the base portion is in a state where one end portion in the length direction Y is inserted through the insertion port 21. 10 is arranged. At this time, in the saddle stitching machine 1, one end portion in the longitudinal direction Y of the sheet 2 is placed on the bottom surface portion 31 b of the magazine 31 of the stapler portion 30 and the upper surface portion 20 t ( It is prevented from being inserted into the gaps h1 and h2 between the tip portion of the inclined portion 20f and further guided to the insertion port 21 of the beam portion 20, so that the sheet 2 can be easily moved in the longitudinal direction Y. The one end portion can be disposed on the base portion 10 in a state where the one end portion is inserted through the insertion port 21.

  Next, as shown in FIG. 5, in the saddle stitching machine 1, the guide member 40 is rotated to the other end side in the height direction Z, and the sheet 2 is moved to the base portion by the press holding portion 46 of the guide member 40. 10 is pressed and held. At this time, the sheet 2 is fitted with the fold 2a in the press holding portion 46 of the guide member 40 formed in a substantially V shape, and the convex holding portion 46 of the base member 10 is pressed by the press holding portion 46 of the guide member 40. By being pressed by the guide part 12b and provided along the guide part 12b, the crease 2a and the clincher 11 are aligned. Further, the paper 2 is pressed against the convex portion 12 of the base portion 10 by the pressing holding portion 46 of the guide member 40, thereby preventing paper misalignment due to the subsequent binding operation. Further, since the guide member 40 is provided at a substantially central portion in the width direction X of the upper surface portion 20t of the beam portion 20, the crease 2a of the sheet 2 is formed more than when provided at a position offset in the width direction X. It can prevent arrange | positioning diagonally with respect to the convex part 12. FIG.

  Next, in the saddle stitching machine 1, the paper 2 held by the pressing holding portion 46 of the guide member 40 is stapled at several places along the fold 2 a by the stapler portion 30.

  As described above, the saddle stitching machine 1 performs saddle stitching on the paper 2.

<4. Explanation of effects>
As described above, the saddle stitching machine 1 to which the present invention is applied includes the base portion 10 having the convex portion 12 provided with the clincher 11 and the paper disposed integrally with the base portion 10 and disposed on the base portion 10. 2 is provided with a beam portion 20 having an insertion port 21 into which one end portion of 2 can be inserted, and a stapler portion 30 provided on the beam portion 20 and binding the paper 2 disposed on the base portion 10. Can be placed on the base portion 10 having the convex portion 12 in a state in which is inserted through the insertion opening 21 of the beam portion 20. Therefore, the saddle stitcher 1 does not need to be provided with the size of the base portion 10 in the length direction Y so as to correspond to the size of the maximum size sheet 2 to be saddle stitched, and the conventional base portion has a convex portion. The base unit 10 can be made smaller than the formed saddle stitcher. Therefore, even when the saddle stitching machine 1 is a saddle stitching machine in which the convex portion 12 is formed on the base portion 10, the fold 2 a of the paper 2 is accurately positioned with respect to the clincher 11 of the base portion 10. In addition to being able to be downsized, it is possible to have excellent storability and portability as well as excellent workability capable of working even in a small work space.

  Further, in the saddle stitching machine 1, the lower surface portion 45 b of the guide portion 45 of the guide member 40 is disposed on the other end side in the height direction Z with respect to the bottom surface portion 31 b of the magazine 31 of the stapler portion 30. Is also disposed on the other end side in the length direction Y, and is disposed so as to be substantially the same height or lower than the upper surface portion 20t (tip portion of the inclined portion 20f). Therefore, in the saddle stitching machine 1, when one end portion in the length direction Y of the paper 2 is inserted into the insertion opening 21 of the beam portion 20 by the guide portion 45 of the guide member 40, the length direction Y of the paper 2 is determined. Can be prevented from being inserted into the gap between the bottom surface portion 31b of the magazine 31 of the stapler portion 30 and the top surface portion 20t of the beam portion 20 (the tip portion of the inclined portion 20f). One end portion in the length direction Y can be reliably guided to the insertion port 21. Therefore, the saddle stitching machine 1 can improve the insertability of the paper 2 and improve the workability.

  Further, the saddle stitching machine 1 substantially holds the sheet 2 placed on the base portion 10 at a position corresponding to the top surface portion 12 a of the convex portion 12 of the guide member 40 by pressing it against the convex portion 12 of the base portion 10. A V-shaped pressing holding portion 46 is formed. Therefore, the saddle stitching machine 1 is configured such that the sheet 2 is pressed and held on the convex portion 12 of the base portion 10 by the pressing and holding portion 46 of the guide member 40, so that the press holding portion 46 of the substantially V-shaped guide member 40 and The fold 2a of the paper 2 is fitted, and further, the paper 2 is provided along the convex portion 12, and the fold 2a of the paper 2 and the clincher 11 of the base portion 10 can be reliably aligned. Furthermore, the saddle stitching machine 1 adjusts the binding position of the sheet 2 by the operator by aligning the crease 2a of the sheet 2 and the clincher 11 of the base unit 10 by the pressing holding unit 46 of the guide member 40. This eliminates the need for improvement in workability and eliminates the shift caused by human work, so that the binding position can be more reliably aligned. Further, the saddle stitching machine 1 prevents the sheet misalignment due to the subsequent binding operation of the stapler unit 30 by pressing and holding the sheet 2 to the convex portion 12 of the base unit 10 by the pressing holding unit 46 of the guide member 40. be able to. Thus, the saddle stitching machine 1 has a configuration that functions as both a guide member and a press holding member.

<5. Explanation of Modified Guide Member>
The saddle stitcher 1 to which the present invention is applied may be provided with a guide member 60 as shown in FIG. The guide member 60 is a thin plate member. Furthermore, the guide member 60 is bent in a V shape in a second direction opposite to the first direction on the distal end side and a first bent portion 61 bent in a convex shape in the first direction on the proximal end side. The second bent portion 62 functions as the guide portion 45 of the guide member 40, and the second bent portion 62 functions as the press holding portion 46 of the guide member 40.

  Even in the case of such a guide member 60, when the one end portion of the paper 2 is inserted into the insertion opening 21 of the beam portion 20 by the first bent portion 61, the length of the paper 2 is increased. One end portion in the length direction Y can be prevented from being inserted between the upper surface portion 20t of the beam portion 20 and the bottom surface portion 31b of the magazine 31 of the stapler portion 30, and one end portion in the length direction Y of the sheet 2 can be prevented. Can be reliably guided to the insertion port 21. Further, as shown in FIG. 7, even in the case of such a guide member 60, similarly to the guide member 40, the paper 2 placed on the base portion 10 is pressed against the base portion 10 by the second bent portion 62. Thus, the fold 2a of the paper 2 and the clincher 11 can be reliably aligned.

  Further, the saddle stitching machine 1 is not limited to providing the guide member on the beam portion 20, and may be provided on the stapler portion 30.

  For example, the saddle stitcher 1 may be provided with a guide member 70 as shown in FIG. 8 instead of or together with the guide members 40 and 60. The guide member 70 is a tongue piece formed by cutting and raising a part of the bottom surface portion 31 b of the magazine 31 of the stapler portion 30 to the other end side in the height direction Z. Furthermore, the guide member 70 is disposed on the other end side in the height direction Z with respect to the bottom surface portion 31b of the magazine 31 of the stapler portion 30, and is disposed on the other end side in the length direction Y with respect to the beam portion 20, Are arranged to be substantially the same height or lower than the upper surface portion 20t of the beam portion 20 (the tip portion of the inclined portion 20f).

  Therefore, even in such a guide member 70, when the one end portion in the length direction Y of the sheet 2 is inserted into the insertion opening 21 of the beam portion 20 by the guide member 70, similarly to the guide members 40 and 60. In addition, one end portion in the length direction Y of the sheet 2 is inserted into a gap between the bottom surface portion 31b of the magazine 31 of the stapler portion 30 and the top surface portion 20t of the beam portion 20 (the tip portion of the inclined portion 20f). Therefore, one end of the sheet 2 in the longitudinal direction Y can be reliably guided to the insertion opening 21.

  Further, the guide member 70 is formed so as to be substantially parallel to the guide portion 12 b on one end side in the length direction Y of the convex portion 12. Therefore, the guide member 70 can smoothly guide one end portion of the sheet 2 in the length direction Y to the insertion opening 21. As described above, in the saddle stitching machine 1, since the guide member 70 is a tongue piece that cuts and raises the bottom surface of the magazine, it is not necessary to add a new part.

  Further, the saddle stitching machine 1 may be provided with a guide member 80 as shown in FIG. 9 instead of or together with the guide members 40, 60, 70. The guide member 80 is a plate member attached to the handle 33 of the stapler unit 30 toward the other end side in the height direction Z. Further, the guide member 80 is disposed on the other end side in the height direction Z with respect to the bottom surface portion 31 b of the magazine 31 of the stapler portion 30, and is disposed on the other end side in the length direction Y with respect to the beam portion 20. Are arranged to be substantially the same height or lower than the upper surface portion 20t of the beam portion 20 (the tip portion of the inclined portion 20f).

  Therefore, even with such a guide member 80, one end portion in the longitudinal direction Y of the sheet 2 is inserted into the insertion opening 21 of the beam portion 20 by the guide member 80, similarly to the guide members 40, 60, and 70. In this case, one end portion in the length direction Y of the sheet 2 is inserted into a gap between the bottom surface portion 31b of the magazine 31 of the stapler portion 30 and the upper surface portion 20t of the beam portion 20 (tip portion of the inclined portion 20f). This can be prevented, and one end portion of the sheet 2 in the longitudinal direction Y can be reliably guided to the insertion port 21.

  Further, the guide member 80 is formed so as to be substantially parallel to the guide portion 12 b on one end side in the length direction Y of the convex portion 12. Therefore, the guide member 80 can smoothly guide one end portion of the sheet 2 in the length direction Y to the insertion opening 21.

  Furthermore, the saddle stitcher 1 may be provided with a guide member 90 as shown in FIG. 10 instead of or together with the guide members 40, 60, 70, 80. The guide member 90 is a stapler support portion 34. In other words, the stapler support portion 34 may also serve as the guide member 90. Further, the guide member 90 is disposed across the bottom surface portion 31 b of the magazine 31 of the stapler portion 30 and the top surface portion 20 t of the beam portion 20, and the end portion 91 on the other end side in the length direction Y is from the beam portion 20. Is also arranged on the other end side in the length direction Y.

  Therefore, even in such a guide member 90, one end portion in the longitudinal direction Y of the sheet 2 is inserted into the insertion opening 21 of the beam portion 20 by the guide member 90, similarly to the guide members 40, 60, 70, 80. When inserted, one end portion in the length direction Y of the sheet 2 is inserted into a gap between the bottom surface portion 31b of the magazine 31 of the stapler portion 30 and the upper surface portion 20t of the beam portion 20 (the front end portion of the inclined portion 20f). It is possible to prevent this from happening, and the one end portion in the length direction Y of the sheet 2 can be reliably guided to the insertion opening 21.

  Furthermore, the guide member 90 is formed so that the end 91 on the other end side in the length direction Y is substantially parallel to the guide portion 12 b on the one end side in the length direction Y of the convex portion 12. Therefore, the guide member 90 can smoothly guide one end portion in the length direction Y of the paper 2 to the insertion port 21. Thus, in the saddle stitching machine 1, since the stapler support portion 34 also serves as the guide member 90, it is not necessary to add a new part to provide the guide member.

  Furthermore, the saddle stitcher 1 may be provided with a guide member 100 as shown in FIG. 11 instead of or together with the guide members 40, 60, 70, 80, 90. The guide member 100 is a leaf spring attached over the bottom surface portion 31 b of the magazine 31 of the stapler portion 30 and the lower surface portion 20 b of the beam portion 20, and serves as a return spring of the stapler portion 30 and a guide member. . Further, the guide member 100 is attached across the bottom surface portion 31 b of the magazine 31 of the stapler portion 30 and the lower surface portion 20 b of the beam portion 20, and is disposed on the other end side in the length direction Y from the beam portion 20. Has been. The guide member 100 is provided substantially in parallel with the guide portion 12 b of the convex portion 12.

  Therefore, even in such a guide member 100, one end portion in the longitudinal direction Y of the paper 2 is inserted through the beam portion 20 by the guide member 100, similarly to the guide members 40, 60, 70, 80, 90. When the sheet 2 is inserted, one end portion in the longitudinal direction Y of the sheet 2 is a gap between the bottom surface portion 31b of the magazine 31 of the stapler portion 30 and the top surface portion 20t of the beam portion 20 (tip portion of the inclined portion 20f). Can be prevented, and one end in the length direction Y of the sheet 2 can be reliably guided to the insertion opening 21. Thus, the saddle stitching machine 1 serves as both a return spring and a guide member.

<6. Description of Modified Example of Saddle Stitcher>
The saddle stitcher 1 to which the present invention is applied is not limited to attaching two stapler portions 30 to the upper surface portion 20t of the beam portion 20, but attaches three pieces as shown in FIGS. You may do it.

  For example, on the upper surface portion 20t of the beam portion 20, the first stapler portion 30a, the guide member 60, the second stapler portion 30b, and the third stapler portion 30c are arranged in this order from one end portion to the other end portion in the width direction X. Is done. At this time, the clincher 11 is provided on the top surface portion 12a of the convex portion 12 at positions corresponding to the first stapler portion 30a, the second stapler portion 30b, and the third stapler portion 30c. The first stapler portion 30a, the guide member 60, the second stapler portion 30b, and the third stapler portion 30c all have the same configuration as the stapler portion 30 and the guide member 60 described above, and will be described here.
